First, find a nice green spot to park yourselves in. Easier said than done. What you will find is either the landscaped middle of a roundabout or perhaps a triangle of well-tended lawn bounded by three streets, which is where we settled.
Second, install a slack line between a couple of trees and have your man practice his equilibrial skills in plain sight of passing motorists.
Third, have a small, blond child running joyously about, climbing trees, and taking turns at pretending to be all the varied animals in her mental menagerie.
Fourth, have a pregnant blond lady sitting on a blanket in the grass, crocheting a baby afghan.
